SPARK-ARRESTER.

SPECIFICATION forming part of Letters Patent No. 353,379, dated November30, 1886.

Application filed March 29, 1886. Serial No. 196,884.

To all whoml it may concern Be it known that I, MEINRAD RUMELY, acitizen of the United States, residing in La Porte, in the county of LaPorte and State ofv Indiana, have invented a new and useful Improvementin Spark-Arresters, of which the erally used in close neighborhood tostraw andy wheat stacks, and as the nature of the fuelstraw is such thata large number of sparks is generated, the danger from fire, especiallyif there be any wind blowing, is very great. I overcome this difficultybyapplying to thetip of the smoke-stack a revoluble spark-screen, whichswings into position by the action of the wind,and is contrived toprevent the sparks in any great quantity from escaping into the air.

- The nature of the means I employT to accomplish this result will bebetter understood from the following detailed description thereof andthe accompanying drawings,which form a part of this speeiiication, andin whichn Figure l is a side elevation of my improved smoke-stackscreen. Fig. 2 is an end elevation of the same. Fig. 3 is a top orplanview of the screen with the upper wire-cloth removed in order to moreclearly show the interior. Figs. 4 and 5 are enlarged detail views ofportions of the previous figures.

Upon the drawings, A represents a smokestack of the usual form. At thetop or escapeaperture for the smoke I provide a cone, B, inverted, andhanging in the aperture. It is hinged at one side, and provided at theother with a rod, b, by means of which it may be shaken when it isdesired to free it ofcliuging particles that may have accumulated uponit in the passage of the smoke through the meshes of the wire-gauze, of.which said inverted cone is composed.

Upon the top of the smoke-stack I mountan oblong frame-work, coveredwith wire-gauze at the top, bottom, sides, and one end, forming a hood,with. one end open to constitute a mouth, which open mouth is to be kepttoward the point of the compass from which the wind blows. Thisopen-mouthed hood I have let- (No model.)

tered C, themouth being at c. 4 The hood is mounted pivotally upon thetop of the stack, in any suitable manner so that it may be turnedreadily. A good way to mount it is indicated at Figs. 4 and 5,wherein eisa ring attached to the frame-work of the hood, and riding between twosets of rollers, e e', mounted in the ring ez at the top of thesmokestack A. At the end ofthe perforated hood or box C which isfarthest from the open mouth I provide a discharge-tube, D,wl1ich may beconnected at its upper end by a funnel with the interior of the hood.This discharge-tube D leads down to near the ground, if desired, andserves to convey the sparks and cinders which fall into it to a place ofsafety. At the lower discharge of this tube a circular trough forcontaining water may be located,`sothat the end of the tube in swingingthe hood around the stack will always be over some part of the trough;or a tub or vessel of water of any kind may be used for this purpose. Itwill be sufficient, generally, however, to discharge the sparks andcinders directly on the ground.

Of course the hood may be moved around by hand; but I prefer toconstruct it i-n such manner, by pivoting it at the point indicated inthe drawings, that the wind will swing it in the right position, like avane, and to facilitate this and aid the wind by giving it a goodpurchase I mount upon the boX or hood a vane, F. (Shown at Figs. l, 2and 3.)

The minor details of the structure herein described may of course bevaried to a considerable extent, and I do not desire to be limited in'this respect in the exact construction shown.

The mode of operation of the invention is as follows: The smoke, sparks,and cinders passing up out of the stack, such of them as are not caught,deflected, or turned back by the.

inverted cone B pass up into theinterior of the gauze or perforatedhood, and by the wind blowing into the open mouth of said hood arecarried back to the rear thereof, and the larger portion, if not all,fall into the tube D, and are conveyed by it to the water-vessel or tothe ground. The open mouth of the hood is kept toward the wind, eitherbyhand or by the force of the wind itself. Of course the tube D may bedispensed with, in which case the cinders and sparks would collectin thetail of thehood,

vroo

whence they could be removed as required7 but not so conveniently as bymeans of the tube.

By reason of the hood being made of Wire screening or perforatedmaterial, the air which crowds into its Open mouth passes with more orless freedom through it, and the sparks and einders are conveyed thus tothe farther end of the hood.

I Claiml. The revoluble hood for smoke staoks, pivoted to the top of thesmoke-stack in such manner Aas to be Capable ofA being,` turned with itsopen mouth toward the Wind, substantially as speeiied.

2. The eombination,with therevoluble openmouth perforated hood, of avane for holding the hood in position to the Wind, substantially asspecified.

3. The combination of the perforated openniouth revolubie hood, thesmoke-stack to which it is pvoted, and the interior inverted cone orScreen B, Substantially as specified.

4. The combination, With the smoke-stack A, the interior invertedperforated eone,B,at taehed to the stack in such manner that it may beshaken, of the rod or pull b, Connected to the cone or its support insuch manner that the cone may be shaken by power applied to said rod orpull, substantially as specified.
